Name

ST_LinestringFromWKB — Makes a geometry from WKB with the given SRID.

Synopsis

geometry ST_LinestringFromWKB(bytea WKB);

geometry ST_LinestringFromWKB(bytea WKB, integer srid);

Description

The ST_LinestringFromWKB function, takes a well-known binary
representation of geometry and a Spatial Reference System ID (SRID)
and creates an instance of the appropriate geometry type - in this case, a
LINESTRING geometry. This function plays the role of the Geometry
Factory in SQL.

If an SRID is not specified, it defaults to 0. NULL is
returned if the input bytea does not represent a
LINESTRING geometry. This an alias for ST_LineFromWKB.

OGC SPEC 3.2.6.2 - optional SRID is from the conformance suite.

If you know all your geometries are LINESTRINGs, it's more
efficient to just use ST_GeomFromWKB. This function just calls
ST_GeomFromWKB and adds additional validation that it returns a
LINESTRING.
